| 74F38 Quad Two-Input NAND Buffer (Open Collector) April 1988 Revised September 2000 74F38 Quad Two-Input NAND Buffer (Open Collector) General Description This device contains four independent gates, each of which performs the logic NAND function. The open-collector outputs require external pull-up resistors for proper logical operation. Ordering Code: Order Number 74F38SC 74F38SJ 74F38PC Package Number M14A M14D N14A Package Description 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-120, 0.150 Narrow 14-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 14-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Devices also available in Tape and Reel. Specify by appending the suffix letter "X" to the ordering code. Logic Symbol IEEE/IEC Connection Diagram Unit Loading/Fan Out U.L.
